UNlTEl) AUTOMOBILE RADIATOR.

Application filed July 8, 1921. `Serial No. 483,121.

A principal object of my invention is to provide a radiator forautomobiles in which the core is readily removable from its outer frameor casina` for repair or replacement.

A further obiect of my invention is to provide a circulatory watersystem for -an automobile radiator, particularly adapted for thoseautomobiles in which a water circulatinnv pump may be dispensed with. iA still further object of my invention is to provide a new and improvedform of water inlet and outlet for an automobile radiator.

A still further obi ect of my invention is to provide a deflector ofsuch form and so positioned within the radiator of'an automobile as tocause the heated water cominegrfrom the engine of the automobile to bethrown first towards the sides of the radiator and of the receiving tankand away from the outlet of the tank.I thereby assisting in the cooling`of the water before it is fed back to the en- A still further obiect ofmy invention is to provide an automobile radiator in which the lower orreceiving tank is contained within a removable core.

My invention further includes all of the other various obiects and novelfeatures of construction and arrangement hereinafter more definitelyspecified and described.

In the accompanying drawing; I have illustrated one embodiment of myinvention as applied to Ian automobile radiator in which the core is ofthe wellknown honeycomb construction, the embodiment shown being of aconstruction and design suitable to replace corresponding parts withwhich a Ford automobile is usually equipped.

In the said drawing, Figure 1 is a rear perspective view of theinvention with the i The outer casing' or shell 1 is preferably made ofcast-metal, such` as aluminum or other suitable metal, as an integralunit and having in its upper portion a tank 2 eX- tendinp transverselyacross the casing. The

vertical sides 3 of the casing are providedy with lugs 4 having holes 5through which bolts may be passed to attach the casing`l to theautomobile frame in a usual manner. An overflow pipe 6 communicates withthe Vtank 2 and a brace rod 7 is provided ing' the automobile hood.

An inlet. pipe 8 connected with thel automobile e'ngine communicateswith tank 2 and is adapted to discharge the water upwardly against adeflector 9 which, -as shown.y prehose conveniently heldY in position byhose clamps 16 or in any other suitable manner.

The core 15, which is preferably unitary,

may be of any type suitablev for effecting the cooling; of the water inthe radiator and of such shape as to generally conform to the opening'1'? of the casing', the form illus- 'trated being of the well-k`nownhoneycomb construction comprising a plurality of horizontally andvertically extending` sheets of thin metal positioned closely togetherand providing numerous small passages through which the water circulatesduring' the cooling operation. At the bottom of the raditor c-ore isprovided a header tank 18 which is provided with a water connection 19connected with the engine of the automobile. The upper and lowersurfaces of the metal from which the header tanks 14 and 18 are formed,join vertically extending sides 20 of the core which are preferablyextended rearwardly somewhat beyond the rear face of the portion 15 toform flanges 21 provided with bolt holes 22.

For securing the core in assembled position within the shell or casing`I previde for supportthe shell with a pair of rearwardly projectingflanges 23 provided with bolt holes 24 adapted to register with theholes 22. Through the holes 2a and 22 are passed bolts 25 which aresecured in position by nuts 26.

I preferably provide the front of the core with a peripheral outwardlyextending flange 27, which, when the core is assembled in the casing,rests adjacent the Yfront ofthe casing concealing the joint between theparts, as best shown in Fig. 4f.

I have found that. by my improved form of inlet pipe or conduit 8 athorough circulation of water from the vengine to vthe radiator-core issecured. In .those .cooling systems wherein there is no -water.circulating pump, the circulation ofthe cooling fluid -is produced bythe .heating and cooling of the said duid. vThe.holt'watercoming fromthe engine is lighter than the .cooler water Aleaving the radiator and:the speed of the movement of vthe cooling system depends upon "theamount or feXtent to which the temperature is reduced by .the radiator.If, therefore, the water entering the tank 2 were to be permitted toflow directly back into the outlet l0, the water at the Acenter ormiddle lof the tank would be yhot 'while the water .at the yends or:sides of the tank would `be cooler, more :or .less stagnant, and.inoperative and substantially reduce l.the temperature of the incominghot `water.

By causing the incoming 'hot lwater to circulate in the tank from thefi'nlet in the .middle of the .tank outwardly to :the lsides -of 'thetank 4and vthen back .to the'outlet 10, a substantial reduc-tion of :thetemperature of the water .is yobtained in the tank and the waterentering the outlet in ithe `tank is cooler than :it .is when iit is notrequired to circulate Lback and forth in the tank. The action of theradiator ycore 4is to further cool 'the water. lt will therefore beplain that when :the temperature of the vwater is .substantiallyireducedLin the tank by the .circulation thereof caused by the vdeil'ectors .9,the difference between the itemperature of the water entering theitankand that leaving the core will be greater than 'when the hot waterpasses substantially immediately out of the tank and the speed of theflow of the water in the circulatory system is thus :substantiallyincreased.

It will also be seen that I Vhave provided u radiator which maybedesigned and con- 'structed to conform to those used in standard typesof automobiles, and which Vmay be Acarried in stock by the dealer andIused to replace, temporarily or permanently, dam aged or worn outcorresponding parts.

Repairing ofthe core of my improved radiator may be efficiently andrapidly done by reason of its easy removability from the casing and.replacement therein. This may be done, as will be readily understood,by removing the bolts 25 and disconnecting the water connections withthe engine whereupon thc entire core may be withdrawn from the casing,its replacement being` cor- .respondmgly easy.

vWhile I have found that the casing of my invention may be cast as anintegral unit, it will be understood that it may be formed 'by othermethods, for example by .forming the same from sheet metal, or byforming the same with a number of cast or stamped sections :suitablyjoined together.

It will be understood that variations and changes in the details ofconstruction, arrangementand ylocation of parts would readily suggestthemselves to persons skilled in the art and Vfall within the spirit andscope -of my invention. l do not.desire,therefore,

-to be limited or restricted to the exact de- -tailsof construction and.arrangement shown and described.

Having Vthus described my invention, I

`claim and desire to protect by Letters Pat- Yentof the United States:
